EJB

I'm expanding on an earlier post where I explained how to deploy JAX-RS Web Services to the Oracle Cloud. In that entry the web service simply returned a hard-coded "Hello World". In reality, you most likely want your web service to expose something more meaningful. In this post I'm going to expand the HelloJerseyApp to display the results from a table, which I'll expose using a JPA...

Databases

In Java, implementing via SQL is a well-developed practice for database computation. However, the structured data is not only stored in the database, but also in the text, Excel, and XML files. Considering this, how to compute appropriately regarding the structured data from non-database files? This article raises 3 solutions for your reference: implement via Java API, convert to database...

According to research, most complex report development work can be simplified by performing the data source computation in advance. For example, find out the clients who bought all products in the given list, and then present the details of these clients. In developing such reports, it is the “computation” part and not the “presentation” part that brings about major difficulties. In which stage...
